In the following years, the site was filled in. Hooker capped the 16-acre hazardous waste landfill in clay and sold the land to the Niagara Falls School Board, attempting to absolve itself of any future liability by including a warning in the property deed.  In 1978, however, state officials detected the leakage of toxic chemicals from underground into the basements of homes in the area.  The residents were awarded $20 million in damages by the company; in 1994 the parent company Occidental agreed to pay $98 million to New York to compensate the state for its contribution to the cleanup of Love Canal. The following year the company settled with the federal government for $129 million.
